I love you with all of my heart. You are my best friend. I'm still as attracted to you as I was the first day we met. Though the proverbial bloom is off the rose and I know your flaws and you know mine, we've come so far in working out our differences, and not a day goes by that I don't recognize how lucky I am to have you. I will never leave you - never.
With all of that said... I am sexually still very much alive, and you are sexually dead. I'm sorry I cheated on you. I don't know if we're ever get the "spark" back, that passion. I'm not sure if I can live indefinitely without it. I hope we do. I love you, but I'm still very much a red-blooded young woman who still just wants to get f**ked. And I have.
This is my burden to bear.
